As a child, I loved writing. From age seven I would write and illustrate short poems and stories for my younger siblings to enjoy (hopefully they enjoyed them...). When I was 12 years old, I started leaning towards a more factual side of writing and combined it with my cat obsession to start my own little feline-themed newsletter (I definitely called it a magazine at the time). I'd write about anything felid-related – from tips on adopting streets cats, to the ethics of cloning pets, to the ecology of wild feline species. It was researching for this newsletter that I first learned about the Iberian lynx ( Lynx pardinus ). Initially I was drawn to this feline because it is the only "big cat" native to Spain, where I grew up. ©  Programa de Conservación Ex-Situ del Lince Ibérico

It's World Turtle Day (broad sense of the word turtle, no nit-picking), so this year thought I'd show the progress of a small radiated tortoise (art)study I'm doing. As my Turtle Day drawing last year , 'tis far from finished...

Five years ago today, I set off on one of the biggest adventures of my life. Granted, I'm only 23 and so my life hasn't been particularly long yet and though five years seems an age ago to me, I know it's not really that long ago. To be fair, I haven't even been on that many adventures to compare it with. Regardless... Forest S17. The fragments of Sainte Luce's once bountiful littoral forest are now small from slash and burn agriculture as well as logging. They are numbered S(n), which facilitates their management and conservation.

The grey wolf ( Canis lupus ) is one of the Northern Hemisphere’s most iconic carnivores. However, in a matter of centuries, the grey wolf has been exterminated from at least a third of its former range [1] . Until 2004, wolves remained listed as “Vulnerable” on the IUCN Red List for Endangered Species [1] . The grey wolf is now making an unexpected comeback in North America and Europe [2–4] . A proposal to strip the grey wolf of the protection from the US Fish and Wildlife Service (USFWS) recently sparked debate, leading to an independent review of the species’ situation in North America [5] . Despite the recovery wolves are making, retracting their protected status could reverse this situation once again [5] . What’s more, a mere rise in numbers may not suffice to ensure the future of the species, as extreme population reduction and fragmentation come with less apparent, genetic consequences as discussed below [6–8] . Additionally, as an apex predator, a great deal of controversy...

Plant-insect interactions constitute fundamental component communities of terrestrial ecosystems [1] [2] . The different types of plant-insect associations in nature are thought to have driven both plant and insect radiation [3] . The advantages of animal-mediated pollination have led to the evolution and diversification of specialist mutualisms between, for instance, plants and birds (e.g. [4] ), while the need for protection has spawned mutualisms between various tropical tree species and ants [5] [6] [7] . Herbivory, on the other hand, has led to an arm’s race of plant defence mechanisms and insect attack and feeding habits [3] . An ever-increasing number of studies demonstrate the importance of biotic interactions in driving evolutionary change, but considerably fewer reveal the mechanisms by which this occurs in real-time [8] [9] .

Most plants can reproduce asexually – that is, new plant life is created without the need for female and male sex cells to combine. However, amongst plants there is a variety of ways in which they can reproduce sexually. Sexual reproduction confers certain advantages to organisms: for example, by the remixing of sexual cells, more variation is maintained within a population and there are more likely to be some organisms able to withstand environmental changes. Animal-mediated pollination is a common way by which plants distribute their sex cells to other individuals in a population. Plant have evolved a wide variety of mechanisms to increase the likelihood of pollination, including conspicuous flowers, enticing scents, and sweet nectar rewards. Coffea and Citrus are plant genera which both exhibit attractive flowers and produce more fruit and seeds when pollinated by bees (Ricketts, 2004), which they reward with nectar. However, the nectar of species in these genera contain anoth...

To celebrate World Turtle Day (and here I'm using the word turtle broadly to mean all Testudines/Chelonia), here are some photos of sea turtles I took while snorkelling around León Dormido and Giant Galápagos tortoises on Santa Cruz, both in the Galápagos Islands. Plus a drawing that I don't appear to ever have finished... Drawing turtle wrinkles is really boring. © X O'Reilly
